Once you’ve mounted the shelf to a wall (all you need to provide is a screwdriver), you insert a hardcover’s back cover edge into the little hooks underneath, then close the book over the panel to conceal it from sight. Then, just stack a few more books on top of that. Easy peasy.

Glitch Textiles is a cool studio run by Brooklyn-based artist and designer Phillip David Stearns, where he designs various woven items with “glitchy” digital effect patterns, which are then manufactured using computerized Jacquard looms in the US (for cotton items) and in Holland (for merino items).

This Harry Potter-inspired “Lumos/Nox” light switch cover — designed by Derrick Kendall of Sci-Collectables — is an easy way to add a little magic to any home or office. Fans of the series will know that the wizard spell Lumos creates a bright light at the tip of one’s wand (much like a flashlight), while the counter-spell Nox extinguishes it. This light switch cover takes that idea and runs with it.

The base material of the cover is actually a kind of plastic painted to look like aged copper with a patina (which the two included screws are painted to match) and with a custom raised/embossed design for the words Lumos and Nox. It fits all standard US light switches and is easy to install.

Brightech’s Sparq LED floor lamp is a whimsically modernist, crescent-shaped LED lamp atop a flexible, wire-thin metal stand. It’s one of those things you’ve got to see in person to fully appreciate.

The ultra-thin LED bulb/strip has a color temperature of 3,000 Kelvin, which means it gives off a pleasantly warm, orange-ish glow — about the same as you’d see from a typical incandescent bulb, but without any of the actual heat. In fact it stays cool to the touch even after hours of use, plus it keeps energy usage down to an efficient 15 watts. Perfect for working, reading, or meditating into the late-night hours.

And now we come to the quirkiest (and easily most expensive) item in today’s guide.

This floating “cloud” lamp — designed by the Richard Clarkson Studio in Brooklyn, NYC — is a magnetically levitating LED lamp designed to look like…well, a cloud. Embedded magnetic components in both the cloud and the always-plugged-in base allow the former to float ~2.75″ above the latter. The cloud can rotate, bob up and down, and even light up in a myriad of colors or thunderstorm-like patterns, making the whole thing surreal to look at:

{Infomercial voice} And that’s not all! Check it out:

While the Cloud itself does not have a speaker, it will react to your existing sound system as well as spoken voice and loud sounds. An embedded microphone allows the Cloud to flash to the beat of the music in four different styles. The Cloud also has a range of ambient lamp modes in both white and colored versions. Each of these modes is controlled via an infrared remote.

Basically, this thing is nuts and would look amazing anywhere you put it.

The kicker? It costs $4,620. Obviously not something most individuals are going to buy. I imagine that companies with hip workspaces are the target market for this kind of thing — but hey, if you do decide to buy it for yourself alone, more power to you.
